Tantalum capacitors are available in a wide variety of formats, from discrete components to board-level modules, and are available for many different electronic applications. In this article, we will take a look at 199D476X0035F6B1E3, a type of tantalum capacitor, and the application field and working principle of the component.

Overview

199D476X0035F6B1E3 is a surface-mount, cylindrical, non-solid tantalum capacitor. This type of capacitor is built with two working electrodes; an anode and a cathode, which are separated by a dielectric containing a high concentration of tantalum pentoxide. It is housed in a plastic case usually, and features a jacket sealing the component against environmental conditions.

Application Field

199D476X0035F6B1E3 capacitors are suitable for use in high frequency filtration and energy storage. The device can be utilized in applications such as audio and visual filters, DC-DC converter circuits, automatic control circuits, AC-DC converters, and switching power supplies. Owing to its high capacitance density, 199D476X0035F6B1E3 capacitors are also popular in the aerospace and defense industry, where weight and space are typically major considerations.

Working Principle

Tantalum capacitors work by using the electrochemical principle of an electrolytic double layer capacitor. In this type of capacitor, when the anode and cathode are connected to an electric potential with the oxide layer between them, positive and negative charges are induced, creating a double layer effect. This double layer effect helps to increase the capacitance of the device, allowing for higher energy storage and filtration. In order to take advantage of this effect, the tantalum material of the capacitor must be in intimate contact with the electrolyte, allowing for rapid charge and discharge.

Advantages and Disadvantages of Tantalum Capacitors

Tantalum capacitors offer a variety of advantages, such as low size, weight, and cost, high capacitance, and the ability to be operated at temperatures ranging from -55 to +85 degrees Celsius. Tantalum capacitors offer low self-discharge and are also resistant to impulse voltage. On the downside, they are vulnerable to thermal runaway, must be very carefully matched to the components they are connected to, and should not be placed close to heat sources.

Conclusion

199D476X0035F6B1E3 is a type of tantalum capacitor, known for its high capacitance density and ability to be operated at a wide range of temperatures. It is suitable for use in applications such as audio and visual filters, DC-DC converter circuits, and AC-DC converters, and is often used in the aerospace and defense industry. While tantalum capacitors offer a variety of advantages, they must be handled with care, as they are vulnerable to thermal runaway and must be closely matched to the components they are connected to.
